Photo code: FCS 4/20. Related buildings: Kaukauna Lock 2 complex. NRHP Nomination: This Pony Truss swing bridge utilizes the Warren Truss with verticals design. Anchored to a cut stone foundation immediately down river from Lock 2, the bridge pivots, or swings, at its center. Its ability to turn is facilitated by a large circular gear to which the bridge is attached. Structural members include "I" beams, as well as members that are built of channels and latticework. All connections are riveted. The major variation between this railroad swing bridge Warren Truss, and a conventional highway Warren Truss, is that the top chord taper slightly down at each end. That reduces the weight at each end of the bridge, and promotes the structure's ability to swing. Due to its need to carry extremely heavy loads, the structural members seem disproportionately massive for the size of the bridge. The swing mechanism is electrically operated. This is a contributing element due only to its location in the district, and the fact that it crosses the canal. It is not identified as a property type in Section F, Associated Property Types, because it is a rare element in the district." pony truss bridge
